Abstract (en)
In this invention, disk ID data associated with the characteristics of optical disks are recorded on the innermost peripheral portions of a rewritable optical disk (53) and a read only optical disk (51) in advance. The invention can handle both a rewritable optical disk on/from which data is recorded/reproduced by using both a groove and a land, and a read only optical disk on which data is recorded by recording record marks in a mastering process, and can correctly and quickly identify each optical disk. <IMAGE> <IMAGE>
